What color must the license plate lamp be to meet regulatory requirements?

The license plate lamp must be white to meet regulatory requirements. This is because a white light is essential for adequately illuminating the license plate, ensuring that it is visible and legible for identification by law enforcement and other road users at night or in low-light conditions. The aim of this regulation is to promote safety and compliance on the road by making vital vehicle information easily readable.

In contrast, other colors such as red, yellow, or blue do not meet these requirements as they can obscure the visibility of the plate or convey different meanings unrelated to vehicle identification. For instance, red lights are often associated with warnings or signals, yellow lights with caution, and blue lights with law enforcement presence, none of which serve the primary function of illuminating a license plate.
